Work-search log: how detailed does it need to be? - any advice?

The certification asks how many work-search activities I did and I do not know what qualifies. It has been a long 14 weeks. Some days I only network by email or attend a job fair. What do you record?

I was asked for my log once, after six months. Having it in a spreadsheet made it painless.

Screenshots of the submitted application are handy backup when a posting disappears.
